Before this setting was added in Qt 5.8, the behavior was that
QWebEngineView/WebEngineView got the focus automatically. With the new
setting added it is configurable, but it was left enabled for
compatibility reasons. It would had to be changed at some point anyway:
none of other QML items or widgets grab the focus after creation, so why
would QWebEngineView/WebEngineView do?
This patch also fixes a bug with the text cursor in WebView (the cursor
was blinking as if WebView had the focus when it did not).

focusOnNavigationEnabled setting which allows controlling whether
a web view will receive focus on a navigation request is now disabled

Qt WebEngine implements a custom handler for multiple mouse clicks.

Since https is an internal scheme, it should be in this list of

This also prevents custom custom QWebEngineUrlSchemeHandlers to
register "https". Although it is debatable whether this is necessary,
https should be held to at least the same security standards as http,
which is also in that list.

We now track the values we send to the loadProgress signal. We store
the last value in a new int WebContentsDelegateQt::m_lastLoadProgress
and only send values that are >= m_lastLoadProgress to ensure
monotonicity.
A value < 0 indicates that no loading is going on. Only on loadStarted
it is set to 0 (and a loadProgress is emitted with progress 0) and
on loadFinished, it is set to -1 (and a loadProgress is emitted with
progress 100).
This way, we ensure that you first get a loadStarted signal, at least
two loadProgress signals (0 and 100) and a loadFinished signal
AND all loadProgress signals come in a monotonous order.

The previous code tried to find out whether a user has set an
application proxy by checking the type of the applicationProxy.
This is wrong, because a system proxy will actually also change the
applicationProxy type.

Instead, we now rely on QNetworkProxyFactory::usesSystemConfiguration
to decide whether to use QtNetwork's application proxy, or Chromium's
logic for the system proxy. We also save the state of
QNetworkProxy::useSystemConfiguration to be able to track changes.
